Definitions

  • the proposed invention relates to joint devices for fastening a connective joint and can be used for rapid connecting (disconnecting) pipes or cylindrical cases with round flange elements providing a hermetic sealing of their joints.
  • a disadvantage of this collar for connecting pipes is the impossibility of providing uniform specific pressure on connected surfaces of flange joints at mounting, which can result in arising deformation in a collar cross-section that can, in turn, lead to clearance formation in the latch of the collar and to violation of tightness of the total connection.
  • connection is not intended for joining cylindrical parts with flanges on the ends.
  • the clamp consists of two half rings having an internal ring groove and enveloping closed flanges of connected tubular cables, wherein collar components have projections on the ends, which projections are connected between themselves by an elastic crosspiece on one side, and they have mating latch elements on other side: a clamp in the form of a pin with a plastic cone-shaped tip and a retaining part in the form of a through opening in the projection.
  • the clamp tip on one of projections enters an opening in other projection due to its cone shape and elasticity, and having passed it through, the tip is fixed in that position at the expense of elasticity of a material, since diameter of the tip at its base (at the pin) is a little bit greater than diameter of the through opening of the retaining part, i.e., the clamp is latched.
  • the clamp is provided with a drainage hole in one of its half.
  • a disadvantage of the described construction is that, at the expense of additional fastening clamp elements, joint overall dimensions are increased.
  • a hinged device for connecting pipes as described in U.S. Pat. No. 4,915,418, “Hinged pipe coupling”, URDAN IND USA, Inc., IPC F16L 17/00, -17/04, published on 10 Apr. 1990.
  • the hinged device for connection of pipes is accomplished in the form of several (at least two) segments pivotally connected together by means of hooks and loops. All segments of the device have a circular recess, by means of which they are mounted on closed flanges of connected pipes. At the same time, the ends of extreme segments are pulled together by means of fastening elements such as a bolt and a nut.
  • This construction allows operatively forming a joint device for any diameter of pipes at the expense of a set of necessary amount of segments.
  • a disadvantage of the above-described hinged device is inconvenience of its usage in the conditions of restricted space, since its connecting and fastening elements are arranged on extended parts on the ends of component segments of the device. Another disadvantage of the device is difficult determination of whether the connective joint is closed together sufficiently for providing tightness.
  • This connecting device is intended for fastening the connecting joint and includes two halves connected hingedly with each other.
  • the connecting device is arranged so that, in an operating position, it is engaged with parts of two connection elements which are adjacent to a connecting joint.
  • one end of the connecting device has a fixing element arranged in the form of at least one projection, and other end has a retaining part in the form of at least one recess. Projections and recesses are capable of engaging with each other for transferring connecting halves in an engagement.
  • the described construction provides reliability of connection at the expense of an arrangement of the fixing element and the retaining part.
  • the fixing element (projections) and the retaining part (recesses) of the connecting device are arranged on projections that are normal to the plane of flanges, which arrangement increases joint point dimensions.
  • This device comprises a constricting collar accomplished at least from two half rings with a shaped recess on concave surfaces matching an enveloped profile of closed flange elements, and fixture for collar contraction (studs, screw nuts).
  • the curvature radius of the shaped recess internal surface in each part of the collar in the unclenched position is greater than external surfaces radius of edges of flanges connected between themselves.
  • connection elements have a complicated configuration of details. Elements of fixture in the form of studs with screw nuts and washers increase joint point dimensions. At the same time, process of connecting (disconnecting) flange elements by means of the fastening elements does not allow realization of the process quickly enough.
  • connections with collars are convenient in usage, generally due to fast connecting. However, their applicability is limited by connections that include different fixation elements: bolts, screws, studs, handles, latches, which considerably increase connection dimensions.
  • An object of the claimed invention is creation of a rapid assembly flange joint which does not require secondary fixing members for fixation of connected elements, and which does not increase joint point dimensions.
  • the aforesaid object is achieved for connection of cylindrical elements with round flanges on the ends by a flange joint provided with fixing elements consisting of flanges arranged on end surfaces of connected elements and a connecting device accomplished in the form of a constricting collar, which collar consisting at least from two parts with a shaped annular recess on concave surfaces, which annular recess is matched to enveloped two closed flanges of connected elements in sizes and a cross-section profile, wherein, according to the invention, the annular recess curvature radius in each of parts of the connecting device is equal to radius of external surfaces (edges) of flanges of connected elements, wherein the fixing elements are accomplished in the form of retaining parts on the flanges and retention pins capable of engaging therewith on the connecting device, wherein retention pins are accomplished in the form of the transverse face walls with height equals to depth of a recess on the ends of components of the connecting device, and retaining parts are provided in the form of grooves similarly
  • components of the connecting device envelop in the amount not less than half of circumference of flanges to be connected.
  • retention pins for fixing a position in the constricting collar are arranged directly on its components, while retaining parts in the form of grooves intended to engage with retention pins are arranged on flanges of elements to be connected.
  • connection and fixing of cylindrical elements with round flanges on the ends is carried out as follows. At first, flanges of elements to be connected are aligned so that grooves on them coincide. Then, one of components of the connecting device (for example, a half ring) is oriented correspondingly over an edge of the closed flanges; then one of retention pins made up in the form of the transverse face wall on any of its ends is inserted into one of the aligned grooves arranged on the closed flanges.
  • the connecting device for example, a half ring
  • the second retention pin arranged on the other end of the connecting device component is inserted into the other matching aligned groove on the closed flanges using its elastic deformation, as a result of which there is a latching of the component.
  • the aforesaid operations are carried out in relation of all components of the connecting device, thus realizing connection of closed flanges circumferentially. That is, assembly of the proposed flange joint is carried out very quickly, since it does not require any exact settings, fittings, and screwing.
  • the connecting device envelops flanges of units to be connected, fixing and retaining them in axial direction.
  • components of the connecting device in the proposed rapid assembly flange joint can differ from each other in length, and the number of grooves on flanges to be connected can be more than involved in the assembled flange joint.
  • the number of grooves arranged on both flanges are not less than the number of components of the connecting device, i.e., minimal number of grooves corresponds to the number of engaging therewith retention pins (one or two) of components of the connecting device (collar), and distances between grooves at their minimal number are equal to length of corresponding components of the connecting device arranged on an external surface (edge) of flanges, wherein grooves have width not less than thickness of one or two retention pins intended for engaging therewith. Therefore, components of the connecting device (collar) fix and retain flanges of units to be connected in a cross-section due to the proposed construction.
  • axial fixing and transverse fixing mutually reinforce each other and ensure a safe flange joint.
  • the proposed rapid assembly flange joint has no projecting parts, therefore it does not increase joint point dimensions of cylindrical elements (pipelines, cases) having flanges.
  • depth of grooves made up on flanges can be any depth, and in the particular case of accomplishment, depth of grooves corresponds to height of the projection on flanges over the surface of cylindrical elements to be connected, which reinforces their fixation and reliability of connection.
  • retention pins of the connecting device and grooves provided on flanges of elements to be connected can have various cross-sections (for example, trapezoidal or the right-angled with a swelling at free edge), not coinciding with each other, and in the particular case of accomplishment, profiles of grooves correspond to profiles of retention pins engaging therewith, which reinforces their fixation and reliability of connection.
  • grooves on flanges of elements to be connected can have different width, but not less than thickness of one or two retention pins intended for engaging therewith, and in the particular case of accomplishment, width of grooves intended for engaging with one retention pin corresponds to its thickness, and width of grooves intended for engaging with two retention pins corresponds to thickness of walls of retention pins of two adjacent components of the connecting device, which reinforces their fixation and reliability of connection.
